This item is very similar to our extremely popular Strobe Ball Bopper, but the top ball on the wand has special round dot "windows" that the color-morphing LEDs shine through. Instead of a blurry thick orb of light like the Strobe Ball Bopper, the Windows Wiggle Bopper creates awesome streaking dotted patterns of light as you wiggle the flexible stem. The effect actually kinda reminds us of one of the screensaver patterns on Windows computers (maybe the inspiration for why the manufacturer chose the product name?). Move this around as you dance and you'll be amazed at the huge trails of light that follow your movement. The internal LEDs utilize a powerful RGB high-frequency chip to create the wild color-morphing effect. Each Windows Wiggle Bopper measures about 9" long with a 1.5" ball, and comes with a keychain clip attachment for easy transport. The plastic body of the bopper comes in assorted colors. Uses 4 AG-13 batteries (included and replaceable).
